I included a library in my project that uses cgo, and I got this error when I compile, even with cygwin uninstalled.
I was having cygwin installed first, and try to compile. I read another post that cygwin does not work with cgo, so I installed MinGW-64 for windows. and I got compiled error. Then I uninstall cygwin, still I am getting same problem
